BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pillar for supporting an earth retaining wall, which is installed between a deck plate and an earth retaining wall constructed on a ground excavation surface of various construction and civil engineering sites, It is necessary to provide reinforced concrete installation and concrete installation space in the underground retaining wall space between the structural slab and the retaining wall before completion of the vertical member by the sand bar method which is the weakest part of the construction method, Slab structure, more specifically, easy to install due to easy installation and easy to install regardless of the gap between the wall and the deck plate which is not uniform in the field or other sites, while improving the supporting force The present invention relates to a variable-type filler for supporting a column type earth retaining wall All.

In order to construct an underground structure in various construction and civil engineering sites, it is necessary to excavate the ground to utilize the underground space. In the excavation surface of the ground after excavation of the ground, it is common to construct the earth retaining wall so that the earth does not collapse due to the earth pressure to be.

The construction methods of the retaining wall include pylon wall retaining wall method, Soil Cement Wall method, diaphragm wall method, and CIP (Cast In Place Pile) method. Among these methods, It is mainly used as a method for constructing the basement layer because it has superior stiffness compared with the earth plate wall and soil cement wall method.

A method of constructing the earth retaining wall using the CIP method will be briefly described as follows.

First, an H-file or a prefabricated reinforcing net is placed on the excavation surface of the ground, and the CIP file is poured by filling the concrete with the concrete. After the main thermal type earth retaining wall is vertically installed close to the ground, (For example, an underground space of a high-rise building) is formed inside the main thermal type earth retaining wall by removing the ground after excavating the ground, and a strut (or a welt) is installed to support the main thermal type earth retaining wall .

However, in the case of the construction method using the CIP method, when a large number of CIP files are installed on the excavation surface of the ground, when constructing the continuous continuous wall, that is, the main thermal type earth retaining wall, There is a problem in that the walls of the earth retaining walls can not be uniformly constructed in a straight line because there is a limit in installing them straight.

As a result, there has been a problem that the strut braids (or wales) installed to support the retaining wall are not closely adhered to the retaining wall by location and are spaced apart. In this way, when there is a space between the retaining wall and the strut, the supporting force against the retaining wall is lowered. As a result, the retaining wall is collapsed due to the soil pressure.

In order to solve this problem, for example, a method has been used in which a mold is installed in a spaced-apart space between a retaining wall and a strut (or a wale), and a concrete is laid in the space.

FIG. 1 is a view illustrating a method of constructing a main thermal type earth retaining wall according to the related art.

As shown in FIG. 1, in the method of constructing the earth retaining wall using the CIP method according to the related art, first, an H-file or a prefabricated reinforcing net is inserted into the excavation surface of the ground 1, (p) and the thermal type earth retaining wall body (11) is vertically installed in close proximity.

Thereafter, an earth boring operation is performed inside the earth retaining wall 10 to form an empty space, and then a strut 12 made of H-beam or the like is installed. A deck plate (13) is installed in the horizontal direction so as to intersect with the earth retaining wall (11) at the upper part of the strut (12).

Thereafter, a block-shaped filler (14) is installed between the deck plate (13) and the earth retaining wall (11) to support the retaining wall body (11). Concrete is filled in the spacing space between the end plate 13a of the deck plate 13 and the earth retaining wall 11 to complete the retaining wall.

The method of installing the concrete in the spacing space between the retaining wall body 11 and the strut 13 in such a manner as to enhance the supporting force of the retaining wall will pour concrete into the spacing space between the retaining wall 11 and the deck plate 13 Install the filler (14) before doing so.

However, according to the method of constructing the earth retaining wall according to the related art, the filler 14 made of the steel plate or the H-beam is uniformly cut and then fastened to the end plate 13a of the deck plate 13 by welding, And it is necessary to carry out welding work in a relatively narrow space, so that the work is difficult and the risk of safety accidents is high.

Since the spacing between the retaining wall body 11 and the strut 13 is not uniform at each site, the filler 14 according to the prior art is manufactured at a factory with a size optimized for each site, There arises a problem that it can not be used when the distance between the wall body 11 and the deck plate 13 is changed,

In order to solve such a problem, Korean Patent No. 10-091087 (registered on July 30, 2009) can adjust the length according to the interval between the retaining wall and the wale, The present invention has been made in view of the above problems, and it is an object of the present invention to provide a groove filling apparatus for a banding which can be easily installed and separated and reused.

A groove filling apparatus proposed in Korean Patent No. 10-091087 includes a wall surface supporting member for supporting an earth retaining wall to be installed on an excavation surface of a ground and a wall supporting member for supporting the earth retaining wall by being installed horizontally along a wall surface of the earth retaining wall And a gap adjusting means for adjusting the gap between the wall surface supporting member and the wale support member, wherein both ends of the wale support member are coupled to the wall surface supporting member and the wale support member, respectively.

However, in the groove filling apparatus proposed in Korean Patent No. 10-0910987, the belt supporting member and the wall supporting member are installed between the wale (or the H-beam member) and the earth retaining wall, When the concrete is laid in the spacing space between the retaining wall and the wale after installing the grooving device according to the present invention, it can be easily separated between the retaining wall and the wale without being able to withstand the concrete pouring pressure applied from above.

Further, in the groove filling apparatus proposed in Korean Patent No. 10-0910987, a hook member including a fixing portion, one end of which is fixed to the wall supporting member, and a hook portion, which is hooked on the flange end portion of the other end, However, since the structure of the groove filling apparatus is complicated by the provision of the hook member, the space between the wall supporting member and the strap supporting member can be reduced, It is difficult to adjust the gap due to the interference, and when the concrete is laid due to loosening of the hook portion at the end portion on the flange portion, there is still a problem that it can not withstand the concrete pouring pressure applied from above and is easily separated between the retaining wall and the wale.
